The paper presents the results related to the determination of the index of primary and maximum and minimum indices
of secondary compression, i.e. modified primary and secondary compression indices (Cc, Cc', C'min, C'max), obtained by laboratory
testing of artificially prepared municipal waste samples (three series of 9 samples in total) in an oedometer apparatus with a diameter
of 20 cm. Old municipal waste was used, which was taken from two landfills in Serbia, one that is no longer in use (Ada Huja in
Belgrade) and the other that is still in use (city landfill in Novi Sad). The duration of the test of the first series was 74 days, the second
series 161 days and the third series 147 days. From the results it was possible to present the relationship of these indices and the initial
void ratio as well as the influence of normal stresses on the ratio of modified secondary and primary compression indices (C'max/Cc'
and C'min/Cc'). The established relation can be useful for obtaining the secondary compression index for a significantly shorter
duration of the experiment, since a time of 15 min has been adopted for the completion of the primary compression.
